Abstract

PURPOSE:To obtain the liquid fuel burner in which no nitrogen oxide is produced and a flameless combustion is possible by carrying out a catalytic combustion of a liquid fuel vaporized by a liquid fuel burner by a specific catalyst. CONSTITUTION:When power is supplied to a heating element 2, catalyst 1 is heated and the temperature thereof reaches 200 deg.C, vaporization of the liquid fuel is started by the liquid fuel vaporizing device A. Air sent from a combustion air supplier 11 is mixed with the vaporized liquid fuel in a vaporization chamber 7, and the gaseous mixture is introduced to a mixing chamber 14'. The gaseous mixture which has been amply mixed in the mixing chamber 14' is introduced to the catalyst 1 wherein the gaseous mixture is subjected to a catalytic combustion. When the temperature of the catalyst 1 exceeds 300 deg.C, the power supply to the heating element 2 is stopped. Thereafter, the combustion is continued by the heat generated by the catalytic combustion. The catalyst 1 is composed of a catalyst carrier consisting of lime aluminate and a heat-resisting fundamental aggregate and a catalytic substance composed of a metal selected from the group consisting at least of rhodium, palladium and ruthenium, and platinum.
